Embodiment Construction

[0033] In order to further explain the technical means and functions adopted by the present invention to achieve the intended purpose, the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0034] In related technologies, the working principle of the magnetic navigation system is as follows: a plurality of permanent magnets of different lengths, sizes and shapes that have been designed and actually measured are used, arranged and bonded to form a hemispherical working magnet, and the stepped arrangement of the magnets points to the working area. Two relatively placed hemispherical working magnets jointly build a working magnetic field and a working area. The hemispherical working magnet is fixed on the base of 10 high-speed motors according to the 8-way working mode. Through the movement of the numerical control motor, the single working magnet can complete the front and back, up and down, left and righ...

Abstract

The invention provides a magnetic navigation system. The magnetic navigation system comprises a magnetic field generator and a control system. The magnetic field generator comprises a plurality of electromagnetic units; the magnetic fields generated by the plurality of electromagnetic units can form a working magnetic field, and the working states of the electromagnetic units can be adjusted through the control system, so that different working parameters of the working magnetic field can be adjusted, the magnetic navigator can conveniently and efficiently adjust the working magnetic field according to working requirements, and the running noise is low. Moreover, the magnetic field generator adopts the plurality of electromagnetic units, so that the defects that a permanent magnet adoptedin the prior art is large and heavy in size and inconvenient to transport, install, maintain and repair are overcome, and the occupied area and the requirement on the ground structural strength are reduced. Besides, when the magnetic navigation system is in a non-working state, the electromagnetic units can be closed through the control system to eliminate the working magnetic field, so that placement and use of surrounding objects cannot be affected.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a magnetic navigation system. Background technique [0002] In related technologies, in order to achieve a field strength of 800 gauss, the magnetic navigation system has a large and heavy magnet, which is inconvenient for transportation, installation, maintenance and repair. Moreover, the requirements for the area of ​​the catheterization room and the strength of the ground structure are high, which limits the scope of use. Due to the use of permanent magnets, the magnetic field strength is fixed, and the field strength cannot be changed as required. Moreover, when it is necessary to change the direction of the magnetic field, it is necessary to change the direction of the magnetic field by controlling the movement of the magnet, resulting in high noise and low efficiency. In addition, regardless of whether it is in the working state, the magnetic field continues to e...
